- aramid fibers impregnated with diluting fluid with a polymer matrix blend, comprising an epoxy resin and a hardener, forming the fourth outer composite layer ;
- the rolls were developed by filament winding on the HDPE cylinder, which was coated by a first thermoplastic polymer (PTFE) liner.
- PTFE thermoplastic polymer
- This third and fourth composite layers of the present invention made by filament winding of the rolls are comprised of an epoxy / hardener polymer matrix and fibers or webs, and may optionally further contain nanoparticles or nanocomposites, such as, for example, nanosilicates.
- the polymer matrices of the third and fourth layers of the composite comprise for each 100 parts by weight of epoxy resin, such as bisphenol A diglycidyl ether, from 10 to 20 parts by weight of hardener, such as tetraethylene triethylene amine, and from 0 to 5 parts by weight of nanoparticles, such as nanosilicates.
- the polymer matrices of the third and fourth layers of the composite contain for each 100 parts by weight of epoxy resin, such as the diglycidyl ether of bisphenol A, 13 parts by weight of hardener, such as triethylene of tetraamine, and 1 part by weight of nanosilicate filler.
- the epoxy / hardener system was selected because of its excellent physical and mechanical properties, having a high resistance to corrosion and humidity. Nanosilicates, while decreasing the permeability of the medium, have increased the mechanical strength of the composite material cylinder.
- PAN polyacrylonitrile
- lignin lignin
- a hybrid composite of carbon fibers and glass fibers can be used to reduce costs, in which case glass fiber was used in the longitudinal direction.
